Product overview

Designed for brushless gimbal stabilization, the GM5208-12 Encoder Combo Set uses encoders to track motor position as the system counters camera movement across the pan, tilt and roll axes. It combines AS5048A encoder technology with twin IMUs. The supplied hardware comprises three GM5208-12 gimbal motors, each with an AS5048A encoder and magnet, one Alexmos 32BIT BGC board in the encoder version, and one connecting cable set. The controller board is supplied without an aluminum case.

Each GM5208 motor has a 12N/14P configuration, a hollow shaft and a Ф63±0.05mm outer diameter. Height including the encoder housing is 30.7±0.2mm, and motor weight is 209±0.5g. The 610±3mm leads use #24 cable and a 2.5mm Dupont connector. Working voltage is 3-5S, maximum power is ≤40W, and the operating environment is -20~60℃ at 10~90%RH. At 20V with no load, speed is 456~504 RPM and current is 0.09±0.1 A; the load current is 1A at 20V.
